Crowns cover or “cap” a tooth to restore the normal function and appearance of the tooth. Crowns may be made as all metal, porcelain fused to metal or all-ceramic (porcelain). Crowns are indicated for teeth with very large fillings, teeth that have had a root canal, fractured teeth, worn teeth and misshapen and/or discolored teeth.
As stated above there are many different materials available to restore a tooth with a crown. Each material possesses inherent limitations and specific requirements that must be understood in order to maximize its long term success. This is one of the areas of specialty training a prosthodontist receives while in their training program.
The basic process includes preparing a tooth to receive a crown. This often requires building up the remaining tooth structure prior to tooth preparation. This helps ensure proper resistance to crown removal is present prior to crown insertion and delivery.
Once the tooth is prepared a temporary crown is fabricated. Impressions are made of the prepared tooth and sent to the dental lab technician for the crown fabrication. The provisional crown is temporarily cemented in place.
When the crown is complete you will come back in and the provisional crown will be removed and the new final crown will be tried in. Minor adjustments are usually needed. Once the adjustments are made and you approve the appearance the crown will then be cemented permanently to your tooth.
